Very few are proposing playing Puig instead of Pedri. Too few to make it a general opinion here. Basically, it's Pedri rested more, Puig played more. That's the change to be had imo.
My biggest problem is Puig ONLY got garbage minutes in the league. Did he even play once more than 45 mins in a game? I only see him getting subbed on pretty late in games, a few minutes here and there, or used when the starters (nearly all key players) are rested.
Funny enough, when he did get more minutes, he was actually one of the best players vs Juventus.
